Introduction
When the Delves were introduced on the expansion launch, we also got a new special tier delve. In the first season, this was our Ascended Void foe, Zekvir. It had two difficulties: “?” and “??”. In season 2, the pattern was followed, and we got a new boss who provided a significantly challenging experience. On top of providing a very prominent challenge, this activity is also hit with a FOMO wall. If you don’t clear the “??” difficulty, you might miss the special skin for your Delver’s Dirigible, and this exotic cosmetic might become out of your reach forever. So, ensuring you know all the tips and tricks on defeating the unpleasant goblin Underpin is very important. In this guide, we will run through many important things you need to pay attention to when fighting our Robo-goblin enemy and provide some useful tips to ensure that you’re ready and prepared once you enter his battle arena. We’ll try to go through all the important things that concern this fight. In case if you want to learn more or have someone assist you in the fight itself in the form of coaching. We can provide similar services to this, which can help you even further. You can then potentially apply this knowledge further once a new fight comes and gain some experience to even complete different fights, applying similar logic as you did for Underpin!
Underpin General Overview
Let’s run through the general information and abilities we have on the boss. Underpin is a goblin that is located inside his mechsuit, providing a strong resilience with additional fire and lightning-themed attacks. He can also summon adds and bombs that need to be dealt with quickly. His abilities are the following:
- Flamethrower - This ability targets you or the closest party member (in case you’re running together with someone). After a short period, it unleashes a powerful cone attack dealing big fire damage and leaving a heavy dot afterwards.
- Crush - This powerful attack happens after Underpin jumps and falls after a few seconds. Before the fall, the area is marked where you DO NOT stand, as it deals heavy damage and can wipe you out in no time. On top of heavy damage, you’re also stunned for 4 seconds if you’re hit.
- Signal Cronies - Once he does this, he summons 3 Cronies. These are similar mech-type enemies that cast Molten Canon, which fires orbs at the player after every few seconds, they’re dodgeable, however it is important to clear these mobs as soon as possible as it can be pretty hard to make sure to stay alive with the boss and the ads dropping attacks on you. On top of it, they do constant ticking damage. After you defeat them, they leave a fire on the ground.
- Divert Energy to Shields - After reaching 100 Energy, Underpin casts a strong shield. You need to DPS through this shield as quickly as possible; if you don’t make it in 25 seconds, the boss will heal for 25 % of his Max. HP.
- Time Bomb Launcher - Underpin launches a few bombs that fall on the ground. After 10 seconds, they explode in a 15-yard range. You can use these bombs and kick them at the Cronies to deal large damage to the mobs.
Unlike Zekvir, there are no different or additional abilities on “??” difficulty, so everything is the same mechanically. However, on “??” abilities get significantly more empowered and they deal far higher damage, becoming more lethal. The slightly upgraded changes that are more than only damage increase are the following:
- Time Bomb Launcher - It becomes a bit harder to stay in the melee as the bombs now spawn circles close to the boss after casting them.
- Signal Cronies - Single wave will now have 5 instead of 3 Mobs.
The boss will also have higher HP and his melee will deal higher damage, so optimizing your build and having a bit more sustain alongside correct curios for Brann will be the most important thing to look for.
Brann Curios and Build
It is also important that Brann is prepared like you and that you pick the correct curios and role for our Dwarven friend to assist you. You can either play Brann as a Damage or as a Healer if you’re required to have more sustain, both can work, but it depends highly on your class and spec. Best curios are the following:
- Mechasaur EZ-Build Kit (Combat Curio)
- Globomagnetic Bouncing Grenade (Combat Curio)
- Pocket Factory (Combat Curio)
- L00T RAID-R (Utility Curio)
The above curios will help you with the shield phase and give you any damage you might miss. They proved to be the best ones as a overall damage output and the potential your character will bring against the Underpin.
The Best Strategy
It is important that you make sure that every mechanic is understood correctly and that you execute everything properly. This fight is pretty hard, so don’t get discouraged if you don’t kill him in a couple of tries; it can take a bit longer than expected. Try to improve on the things that you failed at and optimize your CDs and Personals as much as you can. Another important tip that you can use is to bring flasks and potions. Make sure that your gear is enchanted, and in case you have some open gem slots to use them. Every bit of stat can make a difference, and those 1-2 % wipes can be successful tries. Let’s check the best strategies for each ability that Underpin uses:
- It’s important to stay as close to the boss as possible, this is due to the Flamethrower and Crush abilities, it will make positioning way easier if you’re next to the boss. Even if you’re moving away from it, to kick the balls or attack Cronies as soon as you’re done with it, try to position yourself around the boss quickly.
- Save most of your DPS Big CDs when he casts the Divert Energy to Shields - Makes it way easier to hit the window and make sure he never heals during the encounter.
- Make sure to kite the boss at the edge of the room. As the Cronies leave the fire on the ground, you need to make sure that you DO NOT step on them, as they will deal heavy damage. So, avoiding the corpses of the mobs you defeat will be an important thing to pay attention to. Kitting it around the edges makes the process far easier, so it’s a great thing to follow.
- Kick the bombs at Cronies as much as you can. This will make them die way faster, as these bombs deal a big portion of HP once they hit Cronies, so it’ll make any DPS that you might require for them lower, or you will not have to DPS them at all.
- Make sure to bind the interact key to your keyboard or mouse. This will make interacting with the bombs far easier, as it can sometimes be very hard to aim at the bombs if the boss is right next to you. Also, if you’re moving with the mouse, this one can be really painful to navigate around.
- Try to save your Defensive CDs and personals once YOU need them. This also applies to the potions and everything else. Making sure that you can survive the phases or parts of the fight that make your life harder is important. This will differentiate with each player, so make sure that you understand the fight and know when to apply these strategies.
